The weston
Model E.703 is a Lightometer rather than an exposure meter as such. It
reads light values (foot candles) but there is no mechanism to convert
them to exposure settings using shutter speeds, apertures and file speeds.
This neat little unit measures 4 5/8" high by 2 5/8" wide with
a depth of 1 7/16" and weights in at 12 ounces. In the UK where it
was made it was sold with a leather case for £3, 7 shillings and
six pence. That's just under £3.40!

The label
on the US model to the right also says type 7, 100 FC, Viscor & Cosine
Filter, serial # 38554. It was made by the Weston Instruments Division
of Daystrom, Inc.; The meter has a removable screen to provide greater
sensitivity in low light.

It
appears that US based Sight-Light produced a series of exposure meters
based on this model.

A Weston
branded USA made 703 Model 60 is shown opposite.

Also, a model
branded BENJAMIN Lightmeter was made by Sangamo Weston at Enfield - thanks
to David Unwins for the information and pictures. It appears to be the
same as the UK made E703 with the rectangular base and the dial shown
it is made by Sangamo Weston in Enfield. The Weston branded meter is on
the far right.
